Has anyone used one of these? I just picked up a brand new one for $3 at a flea mkt. Hope is comes in handy for yardage calculations.

I have one but basically only use it as a regular calculator. I never did sit down and try to figure out how to use all it's functions

Maybe we can all learn together. :)

I have one also, and don't know how to use it, but I haven't tried either....got mine at Michaels on the clearance shelf...

It is really easy to learn - and the instruction book lived in the back under the little door. Try it - you'll like it.

Love mine when i use it, not very often, but the little booklet that fits in the back of the calculator is very helpful

I love mine. I use it for yardages, calculating fabric cost, converting metric to english for embroidery, etc.
It works great as a regular calculator, but even better for quilting once you learn the functions. The best thing is the instructions store right inside the calculator, so if you forget, you don't have to track down a manual...it's right there!
